Re: how is water getting in my 17 ft aluminum
Assuming you have a Lowe. I have a 2007 FM-175 w/ 115-Optimax.
After a 10-day trip to the Ozarks (bilge every morning) & day trip to Clinton lake, I was taking on water every time I'd launch. Thought it was a bad transducer mount / caulk job after new Humminbird installed. Brought it back to Cabelas to have them check it out. After re-mounting & caulking the transducer, Cabelas found a 6" long tear in the middle of the hull. With a lot of phone calls direct to customer service, they agreed to replace the entire hull instead of a patch. In your driveway put a hose inside the hull and see if you have any leaks.
